deleting libqt4-dbus deleted many packeges

[danielgww]

I was trying to update libqt4-dbus because a program I was going to install needed the next version. I used KpackageKIT on Kubuntu 9.10 to delete the old libqt4-dbus. Somehow I made the stupid mistake to agree to delete all dependency. Now most of may KDE programs are not starting (I dont know, if Kubuntu will start again after turning it of...).

Is there a way to undo it?
Or how can I find what programs where deleted?

Qt

The Qt (> Qt wiki) is the base of the KDE.


Simulation

sudo apt-get -s remove libqt4-dbus

man apt-get

-s, --simulate, --just-print, --dry-run, --recon, --no-act

No action; perform a simulation of events that would occur but do not actually change the system.

When you removed the libqt4-dbus you removed the Kubuntu (KDE). The next time you turn the computer on there won't be graphical log in - there will be the text mode log in.

If you log in you could install the default/basic Kubuntu (KDE) back by the command /1/:

sudo apt-get install kubuntu-desktop

The Devil is in the Details

Your net may or may not work without KDE. Here it is working.

If you have a separate home partition ( > FAQ: How to Partition) then there is an option to reinstall your system without losing valuable personal data.

There is an option (with the alternate CD - does the LiveCD has this option ?) to repair the installation - "Rescue a Broken System".

Introduction

One of the handy features of apt (the packaging system used by Ubuntu) is the use of metapackages. These packages do not contain actual software, they simply depend on other packages to be installed...
